  // EXECUTING: The job is executing.
  // COMPLETE: The trigger has fired and is not scheduled to fire again.
  // ERROR: The trigger definition has an error.
  // DELETED: The job has been deleted.
  // PAUSED: A job can have this state during patch and major releases. After the release has finished, the job state is automatically set to WAITING or another state.
  // BLOCKED: Execution of a second instance of the job is attempted while one instance is running. This state lasts until the first job instance is completed.
  // PAUSED_BLOCKED: A job has this state due to a release occurring. When the release has finished and no other instance of the job is running, the job’s status is set to another state.
